TLDRIn the medical field, accuracy and reliability are crucial, which poses a challenge for the use of Large Language Models (LLMs) due to their tendency to generate incorrect information. To address this, Peter demonstrates the use of Retrieval-Augmented Generation (RAG), a technique that enhances LLMs by incorporating additional information from a database of text sources. This method not only reduces inaccuracies but also provides referenced responses, which are essential for medical professionals. Using a vector database with 3000 medical genomics abstracts from pharmGKB, Peter showcases two demos: one illustrating the difference between LLM outputs with and without RAG, highlighting the increased detail and provision of working PubMed links in the latter; and another demonstrating real-time genome annotation using an LLM with RAG, turning someone's DNA into readable information.

🧬 Introduction to Medical Demos with Groq Powered LLMs

Peter introduces himself and the purpose of the video: to demonstrate medical demos using Groq-powered LLMs. He emphasizes the importance of reliability and accuracy in medicine and acknowledges the issue of LLMs generating false information, known as 'hallucinations'. Peter explains that this has led to slow adoption of LLMs in the medical field. He also mentions the need for doctors to have referenced or sourced information. To address these issues, Peter introduces the concept of Retrieval Augmented Generation (RAG), a technique to enhance the accuracy and reliability of LLMs by providing them with additional information surrounding a query. He explains how RAG works by indexing a database of text sources and feeding the most relevant ones into the LLM to generate responses. The demo will use a vector database containing 3000 medical genomics abstracts sourced from pharmGKB, a database of clinical guidelines for gene-drug interactions.

🔬 RAG Demo: Gene Variants and Warfarin Doses

Peter presents the first demo, which illustrates the classic use of RAG. The demo involves connecting a genomics database to an LLM named Mixtral, running on Groq hardware. For demonstration purposes, Peter inputs a query about gene variants associated with adjusted warfarin doses. The output is shown both with and without RAG. The RAG output provides more detailed information, including missing gene variants and genes, compared to the output without RAG. Most importantly, the RAG output contains working PubMed links, allowing doctors to verify the information. Peter highlights the significant difference in output quality between using RAG and not using it, and how RAG can customize LLMs for medical applications.

🧬 Real-time Genome Annotation with LLMs and RAG

In the next demo, Peter discusses the challenge of using LLMs to annotate the genome, which is typically a slow and difficult process. However, he demonstrates how Llama-2, a 70 billion-parameter LLM running on Groq hardware with RAG, can annotate the genome in real time. Peter provides context by explaining VCF (variant calling format) as a sequence genome that shows a person's gene variants. An example VCF file is uploaded and rendered, with emphasis on the ID column that describes gene variants. The process involves iteratively processing the VCF, searching for matches in the gene-drug database, and summarizing relevant abstracts using the LLM. Working PubMed links are provided for each match. The result is a real-time annotation of someone's DNA, showcasing the potential of LLMs in medical settings when combined with techniques like RAG.

📘 Conclusion: The Role of LLMs in Medicine with RAG

Peter concludes the presentation by reiterating the potential of LLMs in medical settings, provided their reliability and accuracy are improved through techniques like RAG. He thanks the audience for their attention and highlights the successful demonstration of LLMs' capabilities in medical contexts when augmented with RAG.
